You have built a great tool that solves an important issue. But it seems more like a feature than a product. This is something that Github itself should build.
A Chrome extension might help with usability, but extensions have an even lesser user base.
@tombielecki Thanks for the feedback. I do feel like my site solves some real problems. However, I am not sure if GitHub would want to add a feature like this on their site - might be too disassociated from their core mission.
